Re: [PSUBS-MAILIST] Hemisphere Seat Formula
Sean,
That made the news down here in NewZealand.
The game wasn't even close, what have they got
to complain about.

Jon - I didn't get a chance to go over your email last night. A bunch
of hooligans decided to destroy my city in a riot, and I had some
difficulty getting out. I'll take a look at it on Friday.

Greg,
I note that the K250 dome only has a 1/2inch seat welded to the
conning tower. I assume this is because the bulk of the force is
transferred to the conning tower cylinder based on the manner of the
configuration. Mounting a similar dome in a tank head would require a
different and bulkier mount, if not only due to reinforcement
requirements.

Jon,
The dome shape that exerts the highest radial loading should fall
somewhere
around the midpoint between a flat disc and a full hemisphere. I imagine
that the 90 degree segment exerts the peak load but I don't know how to
demonstrate that mathematically.
